Error message from VBoxManage snapshot . . . vminfo . . . implies that UUIDs are not accepted

[intuited]

If an invalid UUID is given to the vminfo operation of VBoxManage snapshot, the error message implies that a VM name must be given. For example, if 123-f00d-baaa-baaa-baaa is the correct UUID of a Machine, but 456-dead-f00d-600d-600d is not a valid snapshot UUID, this happens:

$ VBoxManage snapshot 123-f00d-baaa-baaa-baaa showvminfo 456-dead-f00d-600d-600d

ERROR: Could not find a snapshot named '456-dead-f00d-600d-600d'
Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component Machine, interface IMachine, callee nsISupports
Context: "FindSnapshot(Bstr(a->argv[2]), snapshot.asOutParam())" at line 486 of file VBoxManageSnapshot.cpp

This is probably only really a problem for those learning the VBoxManage tool, who may reach the conclusion that UUIDs are not actually accepted by this operation. It would be better to rephrase the error message to something like "Could not find a snapshot with name or UUID '456-...".

That was fixed sometimes in VBox 4.0.x.
